介孔分子筛的研究进展及国内外专利分析

Research and analysis on domestic and foreign patents of mesoporous molecular sieves

简述了介孔分子筛材料的发展历程、合成机理和应用现状,重点分析了介孔分子筛领域国内外相关专利的分布情况,从公开专利申请量年度分布、技术生命周期、主要专利权人的竞争力、技术侧重点等方面进行统计分析。结果表明,我国对介孔分子筛的研究与国际整体趋势一致,取得了阶段性进展。但与国外具有领先技术的跨国公司相比,在技术掌控上仍存在一定的差距,具有高的水热稳定性和催化活性的介孔分子筛材料的制备和将其应用于工业生产仍是研发的重点和难点。

In this paper, the development process, synthesis mechanism and application status of mesoporous molecular sieves are. briefly iHtroduced. The analysis of mesoporous molecular sieves related patents at home and abroad are foeused,includlog the annual dislribution of the patent applications, technology life cycle, main competition of the assignee,technology tocus, cte.. The results show that the domestic develop trend of mesoporous molecular sieves is similar to that of the global. However, there is still a certain gap with leading technology multinational companies for foreign technical mastery. The preparation and industrial production of mesoporous molecular sieve materials with high hydrothermal stability and catalytic activity are still the R ＆ D priorities and difficulties.
